ATTACH MENT FOR FLOUR-BOLTS.

SPECIFICATION forming part of Letters Patent No. 314,137, dated March17, 1885.

Application filed September 10, 188-1. (No model.)

thereof, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to certain new and useful improvements inattachments to flourbolts, such as are ordinarily employed in mills, bymeans of which the requisite temperature of the bolts may be secured,and'the cloth be prevented from clogging by a discharge-current of airin different directions.

The invention consists in the peculiar construction and combination ofparts to produce this result, as more fully hereinafter described andclaimed.

In the accompanying drawings, which form a part of this specification,Figure 1 is a perspective showing my attachment as applied to flourbolts or reels. Fig. 2 is a vertical central cross-section through oneof the reels with my attachment. Fig. 3 is a detached view showing theadjustable nipple-connection.

A represents a polygonal flour bolt or reel of the ordinaryconstruction; B, the casings which conceal other similar flour-bolts.

C is an air-pipe provided with two series of perforations, a and b, theformer being designed to throw jets of air across the outer face of thebolt, as shown at 0, while the latterdischarges similar jets through thebolt directly toward its axial center, as at d.

D is an air-supply pipe connected at one end to a blower, E, and bymeans of nipples c connects such blower with the pipes 0, there being asmany nipples and pipes as there are flour-bolts in the battery, and theflow of air through such nipples is regulated by the valves 1'. Thepipes O are sleeved on these nipples, so that such pipes may be easilyturned toigive the proper direction to the jets of air, as abovedescribed.

E is a blower having a central entrance for air upon each side, one ofwhich connects by means of the pipe F with any source of supply forheated air, while the opposite side is open to the atmosphere andregulated by a sliding gate, g. The pipe F is provided with a valve, g,by means of which the supply of heated air may be regulated as desired,to

temper the cold-air supply to the proper tema perature to produce therequisite dryness in I the bolts as discharged through the pipe 0.

G is a thermometer, one of which should be placed in each bolt-chest, sothat the operator may determine how much heated air is re quired to keepup the requisite temperature.

Experience teaches me that by the use of this attachment Inot onlykeepthe bolt-cloths in perfect condition, but that I evaporate the moisturearising from the chop in the bolt; and I obtain the greatest possibleresults from such bolts, for by keeping the cloth in the conditiondescribed I am enabled to operate upon nearly if not quite double theamount of chop from the stones or grinders than heretofore.

Vhat I claim as my invention is The bolt A, perforated pipe (3, and pipeD,

in combination with the blower E, having ad j ustable inlets for hot andcold air, as and for the purposes set forth.
